I never realized that taming pets was such an involved process for hunters.
It could be. Think of it like Pokemon in a sense, only you could only tame 5 monsters at a time. My Hunter has plenty of fairly unique pets and I specifically stalked one of them for a couple days (that being the Silithid Ravager, a rare spawn that I accidentally killed the first time around).
I currently have:
Scorponok- teal Scorpid (this one is currently NOT found in Cataclysm)
Dirge- black Wind Serpent (I solo'd Wailing Caverns at lv.21 specifically for this, it was pretty fun, too)
Ayamiss- Sapphire Hive Queen (currently untameable) ~ same graphics as the boss Ayamiss the Hunter
Meltdown- a green slime (currently untameable)
Rampage- aformentioned tan Silithid Ravager
I used to have a Dragonhawk named Divebomb, but I had to give it up to get the green slime before Blizzard fixed it.
I also used to have a red Wind Serpent named Thrust and a white Wind Serpent named Ramjet.
Yes, most of my pets are named after Transformers. That's the theme I went with and that's what I'll continue with especially since Cataclysm is expanding the pet stable to 25 pets.
I don't ever see anyone use the pets I use except for the green slime, which one of my guildmates uses as a heal target when we do Valthiria Dreamwalker. Most Hunters use Flavor of the Month pets, mostly wolves.
